Welcome to the forums, @lightfoot!
Higher res screen - don't bother, it's insanely hard, and rather expensive. As to multicolored lighting, it has to use the key shortcuts (download the ATK driver from ASUS if you need it), and it only comes in white. I don't mind having only one color, since I am interested in lighting up my keys in a dark room for typing, not in making my laptop look "cool".
